Title
(EN) A HEAT EXCHANGER
(FR) ÉCHANGEUR DE CHALEUR
Abstract
(EN)
The present disclosure envisages a heat exchanger (100). The heat exchanger (100) comprises an outer tubular wall (10), an inner tubular wall (20) and a plurality of tubes (30). The inner tubular wall (20) is spaced apart from the outer tubular wall (10). The inner tubular wall (20) defines a tubular space (25) on its inner side. An annular space (15) between the outer tubular wall (10) and the inner tubular wall (20) defines a shell side of the heat exchanger (10) for transmitting a first fluid therethrough. The plurality of tubes (30) is disposed in the annular space (15), which transmits a second fluid therethrough. The provision of the inner tubular wall (20) enhances heat transfer efficiency, optimizes pressure variations and enhances resistance to scale formation on both shell side and tube side.

La présente invention concerne un échangeur de chaleur (100). L'échangeur de chaleur (100) comprend une paroi tubulaire externe (10), une paroi tubulaire interne (20) et une pluralité de tubes (30). La paroi tubulaire interne (20) est disposée à distance de la paroi tubulaire externe (10). La paroi tubulaire interne (20) définit un espace tubulaire (25) sur son côté interne. Un espace annulaire (15) entre la paroi tubulaire externe (10) et la paroi tubulaire interne (20) définit un côté coque de l'échangeur de chaleur (10) à travers lequel un premier fluide est transmis. La pluralité de tubes (30) est disposée dans l'espace annulaire (15), ce qui permet de transmettre un second fluide à travers celui-ci. La présence de la paroi tubulaire interne (20) améliore l'efficacité de transfert de chaleur, optimise les variations de pression et améliore la résistance à l'entartrage sur le côté coque et le côté tube.
